I like sauerkraut on hot dogs or with just about any form of pork, and I too will eat it plain out of the jar. My wife hates it, though, with the sole exception of Reuben sandwiches.
Someday I want to try making my own sauerkraut.
I have a real problem with Reubens.
I tell these waiters to ensure they put LOTS of sauerkraut on it. LOTS! But mostly it’s just another small layer in there.
